The widening gap between rich and poor is leading to segregation in more and more European cities. The rich and the poor are living at increasing distance from each other, and this can be disastrous for the social stability and competitive power of cities. This book provides rigorous comparative evidence on socio-economic segregation from 13 European cities: Madrid, Milan, Tallinn, London, Stockholm, Vienna, Athens, Amsterdam, Budapest, Riga, Vilnius, Prague, and Oslo.
